Polly Plastics Rock Tumbler Media Grit Refill, Medium 180/220 Silicon Carbide Grit, Stage 2 for Tumbling Stones (2 Pack) (6 lb.)

The size of the containers are perfect for smaller tumbler that tumble up to 2 pounds of rocks at a time. For bigger tumblers one would need a bigger volume of grit than these containers. For what they are designed for though, they are about perfect. The grit is very good and works just like it should. There was no delay in the order and the product arrived quickly.

Took a while to arrive...BUT this product is worth the wait.

Used this to resurface my paper sharpening wheel works perfectly and it will probably last me a couple years easily.

It does what it’s suppose to do.

I got the 180/220 grit SiC to use with granite slabs to flatten some Shapton Pro sharpening stones. It worked great. My only complaint is the consistency doesn’t seem as good as some other SiC powder I’ve purchased. It’s supposed to be 180/220 grit but seems finer at maybe 320-400 grit and there’s a lot of even finer dust in it. Still, it worked.

Love it

I purchased this to apply to an MDF wheel mounted to a bench grinder for the purpose of sharpening knives. When applied to the MDF with white glue it chipped right off. When applied to the MDF with real wood glue it adhered very well. A light touch is all that is needed to produce a good edge. These two containers will surely last the average home shop enthusiast many years.

Very good grip and polish does a great job on grinding down and polishing your rocks in the final stage

it was fabulous to find two bottles of grit for my three tumblers at a price point that was very fair.

Good price and quality
